[SOLVED] Problems with ffmpeg and libvpx

lancherider · 01-08-2014, 11:58 AM

Hi all,

I'm trying to use ffmpeg on CentOS 6 to transcode video, but it's hanging up on vpx libraries. Most of the stock CentOS or EPEL stuff was too old so I had to install from source. Here is the output I'm getting:

Unknown encoder 'libvpx'

As you can see, I did compile ffmpeg with the --enable-libvpx option, so I'm stumped on why it's telling me that the libvpx encoder is unknown. I did compile libvpx from source from the latest snapshot, v1.2.0. Any suggestions? Thanks!

try 'ffmpeg -codecs | grep vpx'

i think you have only decode options available

lancherider · 01-09-2014, 08:36 AM

Hmmm, you're right. I wonder why the ffmpeg site lists vpx as a supported codec? Looks like I have some more digging to do, thanks.

ok, i installed libvpx-1.2.0 from git snapshot, installed with

Code:

CFLAGS="-O2 -fPIC -march=corei7 -pipe" ./configure --prefix=/usr --libdir=/usr/lib64 --enable-shared --disable-static

then recompiled ffmpeg with

Code:

CFLAGS="-O2 -fPIC -march=corei7 -pipe" CXXFLAGS="-O2 -fPIC -march=corei7 -pipe" ./configure --prefix=/usr --libdir=/usr/lib64 --shlibdir=/usr/lib64 --mandir=/usr/man --enable-gpl --enable-version3 --enable-nonfree --disable-static --enable-shared --enable-x11grab --enable-libfaac --enable-libfreetype --enable-libmp3lame --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libxvid --enable-openssl --enable-avresample --disable-debug

(just adding --enable-libvpx to be sure); now, my ffmpeg says

Code:

check if /usr/lib*/libvpx.so.1.2.0 exists (but ffmpeg should notice it)

Code:

~/work/ffmpeg-2.1.1$ ldd /usr/bin/ffmpeg | grep "vpx"
        libvpx.so.1 => /usr/lib64/libvpx.so.1 (0x00007f86fce39000)

I was able to get it to work by re-ordering the options in the configure script. Thanks for your input, and thanks to Carl on the ffmpeg-user list that gave me the solution. If anyone wants to see the thread, it's here:

http://ffmpeg.org/pipermail/ffmpeg-u...ry/019292.html

For the morbidly curious, here are the options I used:

--enable-gpl --enable-libx264 --enable-libvorbis --enable-libvpx --enable-nonfree --enable-libmp3lame --enable-libfaac --enable-libtheora --enable-libxvid --enable-pthreads --enable-postproc --disable-debug --enable-shared

Marking thread as solved.
